2dnl Process this file with autoconf to produce a configure script.
3dnl The ONLY thing this is used for is to configure for different
4dnl linux architectures and configurations, it is not used to make the
5dnl code more portable
6
7dnl You MUST have an environment that has all the POSIX functions and
8dnl some of the more populare bsd/sysv ones (like select). You'll also
9dnl need a C++ compiler that is semi-standard conformant, exceptions are
10dnl not used but STL is.
11
12dnl 'make -f Makefile startup' will generate the configure file from
13dnl configure.in correctly and can be run at any time
